The Lawshe family came to America from Rheinland-Pfalz in Germany. Abraham von Laaschet was born in Creyfeldt, Prussia. (The name was Anglicized to Lawshe.) He married Margaret Bechelsheimer, daughter of Elder John Bechelsheimer, minister to the fledging German Baptist congregation in Amwell Township. The Lawshes appear in connection with the church several times in the book A History of East Amwell, 1700-1800.
